Spitfire PR.IV Windshield

The canopy one is the one that shows lots of contour lines with dimensions for each one then it may be, I do have lots of GA images and a dimensional one for the armoured screen, indeed I also have a contour dimensional one for the cowls, but it may be a griffon one.

TonyT, thanks. That is kind of you. I suspect the drawing you have is 39030-1 (2 sheets). I have this one amongst the 3500-ish in general circulation these days. If your drawing is another, then I am certainly interested.

Your posting made me look at the 390 drawing in more detail. There is an interesting note referring to areas that are the same as in Type 350 and Type 351. This is encouraging. Right now I am busy with CAD work on the short engine bearer and cowls, but I think the windscreen will get more attention soon.

Cheers,

The only one I have all the drawing for dimensionally wise etc is for a pressurised version, if any help you are welcome to it.

The ‘blister’ type hood in Mark 12’s picture might be peculiar to the PR.IV as the blisters seem to be seperate items fixed to the hood with screws. The PR.XI version looks to be an integral ‘all in one’ moulding from the pictures I have seen.

“Some PR Spitfires had armoured screens.”

Yup. The one I am working on had a curved one. I see in M&S that some has an armoured screen inside the perspex one.

‘Brilliant pictures, Mark ! Thanks for uploading them.

Cheers,

Some PR Spitfires had armoured screens. 🙂

Then surely the PR IV would be closer to an early Mk I screen.

The PR.IV definitely has a curved perspex windshield. Some of the photos I have seem to show that it may even have slight compound curvature. It is possible that Mk.Id PR aircraft had the flat glass windshield.

I have another question relating to the canopy. Is there a teardrop blister on both sides? All the pictures I have are from the left, and do not clearly show if there is something on the right side.

So, what was the difference between and early and late Mk I screen apart from the external armoured glass?

Many thanks for the responses.

Same basic metalwork but revised perspex to accomodate Armourglass casting.

Screen and canopy are as Mk I later production to Mk V early/mid production but without the external armoured glass and casting.

In the list of drawings held at the RAF Museum Hendon for the F Mk IV Spitfire is one entitled “Windscreen Lines”. This drawing has the number 33730-1D (probably 33730 Sheet 1, size ‘D’). The museum catalogue number is MAC7210.

For the PR Version (Type 353), there is listed only one drawing – 35330-2G (35330 Sheet 2, size ‘G’ ?) with title “Sliding Hood”.

Maybe worth trying them.

I have a perspex for a Mk1 which, as others have said, is the same….I now need to make the lower part of the frame that holds it to the airframe…..I asked for drawings on here, but had no response….(on a Mk1/2 that is)

Please can anyone help with any information, pictures, or best of all, drawings of the PR.IV windshield and frame ? It is a curved one, but unfortunately it is unlikely to be the same as the pressurised PR.XIX windshield.

Screen and canopy are as Mk I later production to Mk V early/mid production but without the external armoured glass and casting.

This metal work carried over to the PR Mk XI but the canopy perspex gained side viewing teardrop blisters.

The PR Mk XIX is totally different and double glazed.

Same as the PR.XI (un-pressurised) I would think. The drawings exist at the RAF Museum and new windscreens have been produced recently – see recent thread on PL965.
